15.4 ECG Calibration

In the process of using the monitor, the displayed ECG signals may be inaccurate due to
hardware or software problems, mainly shown as waveform amplitude becoming larger or
smaller. At this moment, you need to calibrate ECG.
Prepare the following instruments before testing:

ECG simulator

ECG cable

Vernier caliper
The calibration method is as follows:

Connect the ECG cable to the monitor.

Connect the ECG electrodes to the ECG simulator.

Select
 Select [User Maintenance >>] →enter the password and confirm → [User Maintenance]
menu;

Select [Module Maintenance >>] → [Module Maintenance] menu;
 Select [ECG >>] → [ECG Maintenance] menu, and select [Calibration] to calibrate the
ECG;

Measure the wave amplitude with a caliper; in different filtering modes, X0.25 is 2.5 ±
5% (mm), X0.5 is 5.0 ± % 5 (mm), X1 is 10.0 ± % 5 (mm), and X2 is 20.0 ± % 5 (mm).
Comparing the amplitude of the square wave with the ruler, the error range should be
within 5%;

When calibration is complete, select [Stop Calibration] to exit.

15.5 Touch Screen Calibration

You can follow the steps below to complete the calibration of the touch screen:

Select
 Select [User Maintenance >>] →enter the password and confirm → [User Maintenance]
menu;

Select [Cal. Touchscreen] to enter the touch screen calibration interface.

Click on the screen and the alignment mark appears in different positions.
